The clerk withdrew for a few minutes, and returned with the message in his hand. "From George Sheldon to Valentine Hawkehurst, Black Swan Inn, Ullerton," he read aloud from the document. "All right, and thanks," cried the stockbroker. He gave one momentary glance at the clerk, and had just time to see that individual's look of bewilderment as some difference in his voice and person from the voice and person of the black-whiskered man who had just left the office dawned upon his troubled senses. After that one glance Mr. Sheldon darted across the pavement, sprang into his cab, and called to the driver, "Literary Institution, Burton-street, as fast as you can go." "I'll try my luck in the second column of the _Times_," he said to himself. "If George's scheme is what I take it to be, I shall get some clue to it there." He took a little oblong memorandum-book from his pocket, and looked at his memoranda of the past week. Among those careless jottings he found one memorandum scrawled in pencil, amongst notes and addresses in ink, "_Haygarth--intestate. G.S. to see after._" "That's it," he exclaimed; "Haygarth--intestate; Valentine Hawkehurst _not_ at Dorking, but working for my brother; Goodge--letters to be paid for. It's all like the bits of mosaic that those antiquarian fellows are always finding in the ruins of Somebody's Baths; a few handfuls of coloured chips that look like rubbish, and can yet be patched into a perfect geometric design. I'll hunt up a file of the _Times_ at the Burton Institution, and find out this Haygarth, if he is to be found there." The Burton Institution was a somewhat dingy temple devoted to the interests of science and literature, and next door to some baths that were very popular among the denizens of Bloomsbury. People in quest of the baths were apt to ascend the classic flight of steps leading to the Institution, when they should have descended to a lowlier threshold lurking modestly by the side of that edifice. The Baths and the Institution had both been familiar to Mr. Sheldon in that period of probation which he had spent in Fitzgeorge-street. He was sufficiently acquainted with the librarian of the Institution to go in and out uninterrogated, and to make any use he pleased of the reading-room. He went in to-day, asked to see the latest bound volumes of the _Times_ and the latest files of unbound papers, and began his investigation, working backwards. Rapidly and dexterously as he turned the big leaves of the journals, the investigation occupied nearly three-quarters of an hour; but at the expiration of that time he had alighted on the advertisement published in the March of the preceding year. He gave a very low whistle--a kind of phantom whistle--as he read this advertisement. "John Haygarth!--a hundred thousand pounds!"
